I'm still struggling with fuzzy lines — I need to focus on that. Draw more from the shoulder and less from the wrist?
Hey Lamuya! One way to gain 'cleaner' and more confident lines is to draw with less lines, as the fuzziness right now is caused by a lot of lines trying to depict a single line. If you have 10 minutes of time per gesture, and can only draw using 10 lines maximum, where and how would you place them to get as close of a representation of the figure as possible?
Confident lines means single lines! This is especially true for shorter gestures. :) I hope this can help you out.
